Instructions

1. Preheat the oven to 400°F (200°C).
2. In a medium saucepan, bring the water and butter to a rolling boil. Add the flour all at once, stirring vigorously until the dough pulls away from the sides and forms a smooth ball.
3. Transfer the dough to a mixing bowl and allow it to cool for a few minutes.
4. Add the eggs, one at a time, beating well after each addition until the dough is smooth and glossy. Stir in the vanilla extract.
5. Pipe small mounds of dough onto a baking sheet lined with parchment paper using a piping bag fitted with a round tip.
6. Bake in the preheated oven for 20-25 minutes, or until the cream puffs are golden brown and well puffed.
7. While the cream puffs are baking, prepare the pastry cream. Heat the milk in a saucepan until hot but not boiling.
8. In a separate bowl, whisk together the sugar, cornstarch, and egg yolks until well combined and pale in color.
9. Gradually pour the hot milk into the egg mixture, whisking constantly to prevent curdling.
10. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until the mixture thickens to a custard-like consistency.
11. Remove from heat and let the pastry cream cool completely. Once cooled, fill each cream puff with the pastry cream using a piping bag.
12. Stack the cream puffs into a tower, starting with a wider base and tapering off towards the top, forming a cone shape.
13. Drizzle the caramel or chocolate sauce elegantly over the top of the tower.
14. Decorate with dollops of whipped cream and dust generously with powdered sugar.
15. Serve immediately and enjoy the delightful blend of textures and flavors.
